Chebyshev polynomials of the first kind, ?n(?), are defined recursively as follows: ?0(?) = 1, ?1(?) = ?, and ??(?) = 2???−1(?) − ??−2(?), for ? > 1.

I have to write a function with header y = myChebyshevPoly1(n,x), where y is the ?-th Chebyshev polynomial of the first kind evaluated at xy is the ?-th Chebyshev polynomial of the first kind evaluated at xy is the ?-th Chebyshev polynomial of the first kind evaluated at x Be sure your function can take array inputs for x. Use your function to evaluate ?5(?) for ?? = [1 2 5 6 9 18 21 14 3 8 ] /26.

Could anyone help me?

Thanks in advance
